FILTERING APPARATUS Filed Jan. 27, 1930 5 Sheets-Sheet 3 ATTORNEYPatented Feb. 3, 1931r UNITED SATES WILLIAM J. VILLAVASO, OF NEWORLEANS, LOUISIANA FILTERING APPARATUS Application filed. January 27,1930. Serial No. 423,761.

This invention relates to filters especially designed for filtering andvclarifying naphtha, high-test gasoline, Stoddards solvent and otheriiuids used as cleaning agents for dry cleaning clothes and otherfabrics.

Another object of the invention is the provision of a filter for theabove purpose which will eliminate the water bath commonly employed,means being provided for removing 'ro water vfrom the cleaning agent, asWell as for the removal of all other foreign matter during the filteringoperation.

Another object of theinvention is the provision of a filter which willoperate under '-5 pressure to filter a cleaning agent in a relativelyshort time, rendering it unnecessary for an establishment to carry alarge quantity of cleaning agent or solvent, which together with the useof a ltering agent of ffl low cost provides for an economy of operation.

Another object of the invention is the provision of ay filter which, inaddition to the above stated and other advantageous feai tures, may beconnected in any of the dry cleaning systems without disturbing.V theirline-up or arrangement. n i

V] ith the above and other objects in view, the invention furtherincludes the following 2" novel features and details of construction,

to be hereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

Y In the drawings 5 Figure 1 is a vertical sectional view through afilter constructed in accordance with the invention.

Figures 2, 3 and 4 are sectional views taken respectively on the lines2-2, 3 3 and 4-4 9 of Figure 1.

Figure 5 is a detail elevation of the ltering chamber.

Figure 6 is an elevation of the cap.

Figure 7 is a like view of the screen carrying` annulus.

Referring to the drawings in detail wherein like characters ofreference` denote corresponding parts, the reference character 10indicates the housing of the filter which is w provided with an inclinedbottom 11 and a drain 12, the latter' being controlled by a valve orcock 13.

The upper end of the housing 10 is flanged as shown at 14 and is closedby a plate 15 which is removably secured in place by' 55 clamping nuts16, While a suitable gasket 17 is interposed between the iiangev 14 andthel plate 15. e

Located within the housing 1() is a container 18 which provides afiltering chamber 19, G0 the latter being designed to contain afiltering substance or agent such as fullers earth. The upper end of thechamber 19 is provided with an annular flange 20 and removably seatedupon this iiange is an annulus 21. G5 This annulus is preferably formedof copper and is provided with a flange 22 whichrests upon the flange2() and spaces the annulus from the adjacent wall of the filteringchamber. The annulus 21 carries a screen 'm 23 which is clamped upontheupper edge o-f the annulus by a cap 24. This cap is provided withopenings 25 and carries a flange 26 which extends over the annulus 21and is positioned between this annulus and the ad- '55 jacent wall ofthe container18.

The container 18 has extending upwardly therefrom an annular wall 26 ofrelatively large diameter, and extending from this wall is ahorizontally disposed flange 27 which 90 rests upon a flange 28 fastwith and extending inwardly from the housing 10. The flange 28 carriesheaded studs 29 which pass through key-hole slots 30 provided in theflange 27, so that the` flange 27 and conse-l 95 quently the container18 may be detachably. secured to the flange 28 of the housing. he wall26 is provided with inwardly extending hand` grips 31 for convenience ofremoving the container 18.

Openings 32 are arranged around the lower end of the wall 2G so as toprovide communication between the filtering chamber 19 and the interior.of the 'housing through these openings and through the openings 25 inthe cap 24.

The fluid to be filtered may be fed under pressure through a pipe 33which provides an inlet, and the inner end of this pipe has securedthereto one end of a pipe 34. rllhe m9 CFI opposite end of the pipe 34is detachably secured to the upper end of a pipe 35 by means of acoupling 36.

The pipe' extends downwardly through the cap 24 and for this purpose,the cap is provided vwith an opening which is surrounded by a splitsleeve 37. A clamping sleeve 3S is threaded upon the sleeve 37 and isprovided with suitable handles whereby the clamping sleeve may bemanipulated to clamp the sleeve 37 upon the pipe 35.

The lower end of the pipe 35 is closed as indicated at 39 and thisclosed end is threadedly engaged with a nipple 40 which extends downwardfrom the lower end of the container l A screen cap 4l is secured to thisnipple over the closed end of the pipe 35. This pipe is also providedwith openings 4l so as to establish communication between this pipe andthe filtering chamber 19. A screen surrounds the pipe 35 and is spacedfrom the openings.V This screen is carried by a collar 4S and engagesover an annular flange 44 provided at the bottom of the filteringchamber.

rlhe housing is provided with an outlet 45 for the discharge of theltere-d fluid, while a vent 46 provides for the escape of fumes.

Detachably secured to hooks 47 w iich depend from the flange 48 is amoisture bag 49 of suitable material. As shown in the drawings this bagencloses the filter chamber or container 18 and the cleaning agent fromthe chamber 19 must pass through this bagl reach the outlet 45.

A gauge 50 is carried by and is in communication with the interior ofthe housing i0.

l ie cleaning agent to be filtered is supplied to the filter chamberthrough the pipe 3G and enters this chamber through th-e screen 42 so asto eliminate some of the foreign matter. The. cleaning agent is thenforced upward through the fuller-s earth or other granular substancewithin the chamber 1.9 and passes through the openings and and throughthe bag 49 until it has reached a sufficient height to pass outwardthrough the ipe 45.

lll-.Then the pipe 35 is removed for any purpose, the screen cap 41prevents the foreign matter from passing' from the chamber i8 into thewater bag. All moisture is thus prevented from passing` into the housingand out through the pipe 45.

rlhe invention is susceptible of various changes in its form,proportions and minor details of const uction and the right is hereinreserved to make such changes as properly fall within the scope of theappended claims.

Having d-escribed the invention what is claimed is l. A filter includinga housing having an inlet and an outlet, an annular flange in thehousing, a filter chamber in the housing and positioned below theflange, anenlarged portion on said chamber and detachably secured to theflange and having openings, a filter bag supported by the flange andencasing the chamber, a perforated cap closing the upper end of thechamber and having openings, a screen in said cap for closing said lastnamed openings, and a pipe detachably secured to the inlet and thechamber and terminating adjacent the bottom wall of said chamber todeliver fiuid from the inlet to the lower part of the chamber.

2. A filter including a housing having an inlet and an outlet, anannular flange in the housing, a filter chamber in the housing andpositioned below the flange and having a centrally arranged open seat inthe bottom wall thereof, a closure for said seat and removabletherefrom, a filter bag supported by tl e flange and disposed about thechamber, perforated cap closing the upper end of the chamber, anenlarged portion formed on the upper end of the chamber and detachablysecured to the flange and having perforatious therein, a, pipe havingthe lower end received in the seat and extending through the cap andhaving Aperforations arranged` above the bottom wall of the chamber,means l acliably connecting the pipe to the cap, and means connectingthe pipe to the inlet.

P. ji filter including a housing having an inlet and an outlet, anannular flange in the housing, a filter bag` supported by said flange, achamber arranged within the bag and having its upper end enlarged anddetachably red to the flange and provided with periorations, a seatformed in the bottom wall of the chamber, a perforated cap closing theupper end of the chamber within the enlarged portion, a pipe secured inthe seat and eX- tending through the cap and having perforationsarranged adjacent the seat and bottom wall of the chamber', meansdetachably connecting the pipe to the cap, and means detachablyconnecting` the pipe to the inlet.

ln testimony whereof l affix my signature.
